Subject [jira] [Created] (FOP-2993) With PDFBox 2.0.22: Failed to embed font / Illegal offSize value 0 in CFF font
Date Thu, 07 Jan 2021 13:13:01 GMT
Justus Piater created FOP-2993:
----------------------------------

             Summary: With PDFBox 2.0.22: Failed to embed font / Illegal offSize value 0 in
CFF font
                 Key: FOP-2993
                 URL: https://issues.apache.org/jira/browse/FOP-2993
             Project: FOP
          Issue Type: Bug
          Components: font/opentype
    Affects Versions: 2.5
         Environment: Arch Linux
            Reporter: Justus Piater
         Attachments: exception-backtrace.txt, fop.xconf

This bug did not show with PDFBox 2.0.21 and appeared with PDFBox 2.0.22 so it may actually
be a bug in PDFBox (or with this font). However, it may be related to [PDFBOX-5033|https://issues.apache.org/jira/browse/PDFBOX-5033].
Moreover, I have no use for PDFBox besides FOP and don't know how to test the fontbox jar
without FOP.

To trigger this bug, run fop on this this .fo: 
{code:xml}
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <fo:layout-master-set>
    <fo:simple-page-master master-name="one">
      <fo:region-body />
    </fo:simple-page-master>
  </fo:layout-master-set>
  <fo:page-sequence master-reference="one">
    <fo:flow flow-name="xsl-region-body">
      <fo:block font-family="FreeMono">Text</fo:block>
    </fo:flow>
  </fo:page-sequence>
</fo:root>
{code}
 This causes the following exception; the full exception backtrace is attached:

{{Jan 07, 2021 11:44:37 AM org.apache.fop.apps.FOUserAgent processEvent}}
 {{INFO: Rendered page #1.}}
 {{Jan 07, 2021 11:44:37 AM org.apache.fop.pdf.PDFFactory makeFontFile}}
 {{SEVERE: Failed to embed font \[org.apache.fop.fonts.LazyFont@5d25e6bb\{FreeMono}\{metrics-url=null,embed-url=/usr/share/fonts/gnu-free/FreeMono.otf,kerning=true,advanced=true}]
FreeMono}}
 {{java.io.IOException: Illegal (< 1 or > 4) offSize value 0 in CFF font at position
42277}}
 {{at org.apache.fontbox.cff.CFFDataInput.readOffSize(CFFDataInput.java:85)}}

This bug triggers with all GNU Free fonts, but not with any of the other OTF fonts I tried.

I also attach my fop.xconf (with explicit <font> specifications because of FOP-2591).
